Asphalt Paving: A Step-By-Step Installation Guide

There is no end to learning new ideas, particularly when it comes to asphalt paving installation. There are a lot of things that municipality employees and homeowners could learn from this process. From demolition to the laying of a brand new surface, the installation process comprises numerous steps. This brief outlines all the steps as told by construction experts.

Step 1: Demolishing

This step involves removing any existing surfaces, be it concrete, pavers, or asphalt. During the demolition process, heavy machinery may be used, including forklifts and dump trucks. Many construction companies recycle the materials removed from the site, making the process environment-friendly.

Step 2: Grading

For drainage purposes, the second step involves grading the surface. The process requires motor graders and laser-guided transits. The result is a well-prepared surface that enables water to run off smoothly. Water drainage is particularly important to asphalt pavings as water is the leading cause of cracks, potholes, and heaving.

Step 3: Sub-Base Preparation

The sub-base happens to be the most vital part of any asphalt surface. Besides providing anchorage for the new pavement, the sub-base bars entry of frost, thus reducing winter damage resulting from the freeze and thaw effect. With a poorly-compacted sub-base, you won't be assured of long years of servitude.

Step 4: Proof Rolling and Undercutting

Now that the sub-base has been compacted and graded fully, the next step is proof rolling. This ensures the surface beneath is strong enough to carry an asphalt surface. When the proof roll encounters soft spots in the sub-base, the necessary repairs are carried out. This is where undercutting comes in. The process involves digging beneath the surface and substituting the soft clay with a stronger aggregate material.

Step 5: Adding the Binder

With the sub-base laid and soft areas repaired, adding the binder is next. In essence, the binder layer is meant to give the new asphalt surface strength. It comprises a large aggregate mixed with oil and is characteristically durable.

Step 6: Installing the New Surface

After the installation of supportive structures, the fresh asphalt layer is added. The asphalt is made of a small aggregate and mixed with oil and sand. The combination gives the asphalt layer a smooth, shiny, and attractive look once laid.

Step 7: Installing Butt Joints

Since asphalt pavings are usually laid on existing roadways, driveways, or parking lots, there is a need to ensure a smooth transition from the old to the new. Therefore, contractors should fix butt joints in these areas of transitions to make the changes unnoticeable.

After installing the butt joints, it is time to smooth and compact the new surface. To ensure the longevity of your asphalt paving, your contractor should religiously follow the steps outlined above.
